As wrong as in "Don't call most system functions from within a signal

Hmm... In that case, many exceptions would not work either ?
The sigaction handlers for catching exceptions have been fixed quite a while
ago already to only collect the necessary information from the signal
context, and to then return from the signal handler to the start of the RTL
function that handles run time errors, passing this info as arguments (we can
pass at least 3 items on every platform by modifying the parameter register
contents in the signal context; we also change the instruction pointer in the
context so that it returns to the RTL's runerror handler rather than to
wherever the signal was triggered).
Hm.
Quite complex code, and not processor independent.
Is there not a more generic way of handling this ?
Michael.
